DISCLAIMER: Due to my limited knowledge of Japanese and lack of input from the dev team (and thus no context for some things, especially in the fourth installment), I would advise against taking these as definitive; more of a rough guide for the events as I understood them. (I also didn't realize that one AI's ship was called the "Karetsu" until examining KCK 2's text, so KCK 1 reads oddly)

The Ka-co-kh series is an old set of scenarios; like most of the ones from the time (mid-late 90s), it takes place after Infinity and sees the Security Officer working with a new AI, an Earth Defense Force strategist named Nagi. What starts as a conflict between him and another AI, Flea, gradually widens in scale.

Hopper provided the raw texts, and I spent many hours going back and forth between them, Jisho.org, lists of particles and denominations, and Google Translate (for romaji, and knowing where one word ended and another began).

I'm gonna be lazy and cross-post from the Story Forum. :U These posts, written near the beginning of this year, include some additional notes.

Hm...When I asked Logue about JP scenarios, he told me that Marathon Forever and Leopard's Eye (unrelated to the KCK series) were the most popular/well-known on that side of the fandom, so there's that.

In terms of story (and assuming that I interpreted it right), KCK FINAl presents an interesting theory about Durandal and the Jjaro: that Durandal was apparently a Jjaro AI (how he ended up on Mars isn't explained, since he's only mentioned briefly), and that the mistakes the Jjaro made led not only to the creation of the W'rkncacnter and the 'great ruin' it wrought, but one of their own AIs (the fourth of ten, not named) engineering the next generations of Pfhor to specifically target the Jjaro and their remains. There's also the possibility that the Security Officer was around for all this in some form.

'course, this might just be notable to me because I love reading other folks' theories (especially old ones) and examining the thought processes behind them; I do wonder if this was one the JP community of the time posited (leading to broader questions of how they interpreted the Trilogy), or just a personal theory of the scenario creator's.
